Congrats! Rose Byrne and Bobby Cannavale Have Welcomed a Son

It's a good week for Rose Byrne and Bobby Cannavale. The couple welcomed a son on Monday. And the baby boy has the cutest name: Rocco.

During an appearance on The Late Show With Stephen Colbert, the actor revealed that the little one is "doing well." When Stephen asked if the baby was named after Saint Rocco, Bobby responded: "Actually, yeah, patron saint of the sick...pretty sure. Could be wrong. I'm tired." He also joked that he's "gained 28 pounds since Monday" and that he was given a diaper cake by pal Al Pacino.
